# Commerce Lots & Serials

Track product batches with lot numbers and expiration dates, and manage individual unit serial numbers for full traceability.

## How It Works

### Lot Tracking
1. Create lots with production date, quantity, and expiration.
2. Track lot inventory across warehouse locations.
3. Consume, adjust, transfer, split, or merge lots.
4. Quarantine lots for quality issues.
5. Attach certificates (COA, COC, MSDS).
6. Trace upstream sources and downstream consumption.

### Serial Number Tracking
1. Create serial numbers individually or in bulk.
2. Track serial lifecycle: Available -> Sold -> Shipped -> InService.
3. Reserve serials for orders with expiration.
4. Transfer ownership and track location changes.
5. Look up complete serial history with warranty info.

## Usage

- CLI: `stateset lots ...` or `stateset serials ...`
- Writes require `--apply`.
- MCP tools (Lots): `create_lot`, `list_lots`, `get_lot`, `consume_lot`, `adjust_lot`, `transfer_lot`, `split_lot`, `merge_lots`, `quarantine_lot`, `release_quarantine`, `add_lot_certificate`, `trace_lot`, `get_expiring_lots`.
- MCP tools (Serials): `create_serial`, `bulk_create_serials`, `list_serials`, `get_serial`, `mark_serial_sold`, `mark_serial_shipped`, `reserve_serial`, `release_serial_reservation`, `transfer_serial_ownership`, `lookup_serial`, `validate_serial`, `get_available_serials`.

## Permissions

- Read: `list_lots`, `get_lot`, `trace_lot`, `get_expiring_lots`, `list_serials`, `get_serial`, `lookup_serial` — no `--apply` needed.
- Write: `create_lot`, `consume_lot`, `quarantine_lot`, `create_serial`, `bulk_create_serials`, `mark_serial_sold` — requires `--apply`.

## Examples

```bash
stateset lots create --sku PHARMA-100 --quantity 500 --expiration 2026-06-30 --apply
stateset lots trace LOT-2025-A001 --direction downstream
stateset serials bulk-create --sku WIDGET-PRO --prefix SN-W001 --count 100 --apply
```

## Statuses

- **Lot:** Active, Consumed, Expired, Quarantine, Transferred
- **Serial:** Available, Reserved, Sold, Shipped, InService, Returned, Repaired, Quarantine, Scrapped

## Status Flows

**Lot:** Active -> Consumed (or Quarantine -> Released | Expired | Transferred)
**Serial:** Available -> Reserved -> Sold -> Shipped -> InService (or Returned -> Repaired | Scrapped)
**Quarantine:** Quarantined -> Under Review -> Released (or Scrapped)

## Output

```json
{"status":"lot_created","lot_number":"LOT-2025-A001","sku":"PHARMA-100","quantity":500}
{"status":"serial_created","serial_number":"SN-W001-00001","sku":"WIDGET-PRO"}
```

## Present Results to User

- Lot number, SKU, quantity, and expiration date.
- Serial number, current status, and owner.
- Traceability chain (upstream sources, downstream consumers).
- Expiring lots within the requested timeframe.

## Troubleshooting

- Lot in quarantine: must release quarantine before consumption.
- Serial already reserved: release existing reservation first.
- Expired lot: cannot consume expired lots; adjust or scrap.
- Merge conflict: lots must share the same SKU to merge.

## Error Codes

- `LOT_EXPIRED`: Lot has passed its expiration date and cannot be consumed or transferred.
- `SERIAL_ALREADY_RESERVED`: Serial number is reserved by another order; release the existing reservation first.
- `LOT_MERGE_SKU_MISMATCH`: Cannot merge lots with different SKUs; all lots must share the same SKU.
